- L is the length of the reel
- a is the width of the upper cover of the main beam
- b is the length of the upper cover of the main beam
- ⁇ is the angle of the rope of the hoist.
- the optimal solution is that the dividing line ⁇ - ⁇ ' is parallel with the line connecting the vertical center line of the hoisting machine at both ends and the center line of the guiding pulley, and the small yaw angle ⁇ is equal to the hoist at each end of the small yaw angle and
- the guide pulleys are arranged symmetrically.
- the movable pulley blocks in each of the hoisting systems composed of the hoists are connected by a connecting rod.
- the hoist support on the cover plates at both ends of the main beam is arranged in a stepped manner, and the installation height of each guide pulley corresponds to the height of each hoist support.
- the multi-point lifting crane hoisting wire rope space anti-interference arrangement provided by the present invention is realized by a simple structure, and the space anti-interference arrangement scheme of the wire rope system of the hoisting mechanism composed of multiple sets of hoisting systems It is suitable for large lifting height and large span multi-hanging cranes with narrow composite main girder, so that the crane has the following worries when lifting large lifting structures such as drilling platforms:
- the mechanism is simple to arrange, easy to manufacture, install and maintain;
- the hoisting mechanism consisting of multiple sets of hoisting systems is highly efficient
- Figure 1 is a schematic structural view of the present invention
- Figure 2 is a front view of the present invention
- Figure 3 is a plan view of the main beam of the present invention.
- Figure 4 is a schematic view showing the winding structure of the steel wire rope of the present invention.
- the multi-hanger crane hoisting wire rope space anti-interference arrangement is used in multi-hanging cranes for overweight structures such as hanging drilling platforms.
- the crane is usually used for lifting large loads, the main beam height is large, and the width between the main girder webs is small, usually composed of multiple sets of hoisting systems, each hoisting system includes a hoist 1, a guide pulley 2
- the winch 1 includes a reel (including a wire rope press plate), a speed reducer, a brake, an open gear, a coupling, a floating shaft, and the like, that is, a complete drive mechanism from a coupling connected to the motor to a final stage brake.
- the wire rope 6 forms a steel wire occupation area between the guide pulley 2 and the effective portion of the hoisting machine 1, and the area can be characterized by two triangles AABC and AA' B' C' which are the angled top of the guide pulley 2, as shown in FIG.
- the hoisting machine 1 is placed on the cover plate of the main beam 10, and two or more sets of hoisting machines are arranged on the upper cover plates of each main beam; the wire ropes 6 of each hoisting machine are passed along a fixed guiding pulley 2 in the upper space of the main beam cover plate.
- the single rope exit/inlet hole 8 on the upper beam upper cover enters the main beam inner pulley block 5, and then is wound onto the movable pulley block 3, and is repeatedly wound between the movable pulley and the fixed pulley as shown in Fig. 4, and finally fixed at the main
- the beam is fixed on the fixed end 9 of the pulley side.
- each set of hoisting machines on both ends of the main beam adopts hoisting machines 7 of different heights, so that the hoisting heights of the different hoisting reel wire ropes 6 are different, and the formed steel rope occupying faces are not in the same plane;
- the hoist support 7 on the plate is distributed in a stepped manner, and the mounting height of each of the guide pulleys 2 corresponds to the height of each of the hoisting supports 7 as shown in FIG.
- the line connecting the vertical center line of the reel 1 at both ends and the center line of the guide pulley 2 and the center line of the main beam 10 also form a small off angle ⁇ , and the range of the small off angle ⁇ is ⁇ ⁇ , wherein The range of the hoisting angle of the hoist is less than or equal to 2.
